Abstract
Magnetization processes at the surface of iron plates were investigated in a variable external field by means of Mössbauer emission and scattering spectroscopy of57Fe. It is shown that the 90‡ walls of closure domains do not move until an externally applied field reaches a certain value. The “starting” values of the field determined from the Mössbauer measurements agree with those at which a sudden decrease in the growth rate of the bulk magnetization starts. Blocking of the surface domain wall movement occurs in a layer of at least 10 Μm thickness.
